clk: bd718x7: Initial support for ROHM bd71837/bd71847 PMIC clock
Subsystems (2)
PATCH v7 1/1 clk: bd718x7: Initial support for ROHM bd71837/bd71847 PMIC clock
ROHM bd71837 and bd71847 contain 32768Hz clock gate. Support the clock using generic clock framework. Note, only bd71837 is tested but bd71847 should be identical what comes to clk parts.

This is a split from series
https://lore.kernel.org/linux-clk/[email protected]/T/#t
Change history:
v7: (kept the series version number)
- Patches 2, 3, 6, 7, 8 and 9 from v6 were already applied.
- Patches 1, 4, and 5 will be provided as own series touching only clkdev lookups.
- the (already obsoleted) file name was removed from clk-bd718x7 driver
- clkdev lookup registration was removed from clk-bd718x7 driver
Changelog (for the whole series) v6
- Drop 'devm_of_clk_add_parent_hw_provider'. Change 'devm_of_clk_add_hw_provider' to look the parent device node for provider information if device's own node does not contain #clock-cells - property.
- Add kerneldoc in own patch.
- Remove NULL checks from devres match function for clkdev releasing
- Clean styling issues from clkdev.c
Changelog (for the whole series) v5
- Split v4 patch 1. Place clkdev stuff to patch 1 and clk provider to patch 2
- Remove devm_clk_release_clkdev from devres.txt
- Added kerneldoc for managed provider registrations.
- Cleaned styling issues.
Changelog (for whole series) v4
- Add support for ROHM bd718x7 PMIC clock gate. Included in this patch series because it depends on managed interfaces added in patch 1.
Changelog (for whole series) v3
Address issues spotted by Krzysztof Kozlowski
- Drop patch 3 for clk-s3c2410-dclk as this device can never be removed
- Fix indentiation for clk-max77686
- Rest of the patches are unchanged.
Changelog (for whole series) v2
Issue spotted by 0-Day test suite
- Add a stub function 'devm_of_clk_add_parent_hw_provider' for no OF config.
- patches 2-8 are unchanged.
